Why Many Rich Congolese Always Keep Millions Usdollars Under the Grounds

When you ask many  rich Congolese of the East of DRCongo about the reasons of keeping their millions US dollars under the grounds.  Majority of them will point  the Wars And some Rebellions Which are pushing And  supporting by some Westerners And Americans of evil hearts. Rivers and lakes in Congo have more fish  But industrial fishing is not developed due to few modern fishing boats. Congolese engineers are the first black African engineers  who made some marine airoplanes And more luxuries ship of international standards on lake Kivu and  Tanganyika. Why these Congolese riches don't expand on industrial fishing  for more fish  products And  export some raw and cooked fish worldwide? June 25/2023
